The following rules apply to all developers who contribute source code to the Opencaching.de project.

General rules

All source code files must

  • not contain TAB characters,
  • use 4-char indenting columns,
  • be UTF-8 encoded without byte order marks,
  • use only LF as line ends, with the current exception of email templates, which have RFC-822 CR/LF line ends.

There are some tools in the local/devel directory for verifying and fixing these things.

PHP

All self-written or directly changed code must fully comply to the PSR-1 / PSR-2 standard, with these exceptions:

  • When referencing identifiers (e.g. class and function names) that are defined in non-PSR-2-compliant source code files, they need not be PSR-2 compliant.
  • When writing small standalone scripts like those in the 'local' and 'util' directories, they need not to comply to the PSR-1 "Side Effects" rule.

Only <?php and <?= open tags must be used. <? (short open tags) must not be used.
